Source 1
As shown in Figure
PE 1. After the configuration, a share-MDT is established for VPN instance A and VPN instance B
respectively on the public network. After receiving multicast packets from Source 1, PE 1 duplicates and
encapsulates them, and forwards them to PE 2 and PE 3 along the share-MDTs. PE 2 and PE 3
de-encapsulate and forward them to Receiver 1 and Receiver 2 respectively.
Receiver-side PE configuration
To implement multicast across VPNs, this configuration covers creating VPN instance that the multicast
source belongs to on the receiver-side PE, and configuring a share-group for the VPN instance.
